Toadworks John Bull Mk. ii


The ToadWorks John Bull is a guitar effect pedal that emulates the classic overdrive that put Great Britain on the rock & roll map. From the 60's to the 00's, England has produced some of the finest amplifiers on the planet. This is the sound that propelled rock & roll to the global force it is today, and now it's under your thumb, ready to conquer the world all over again. John Bull has been tested and used with a wide range of amplifiers, including tube, solid state and hybrid. If classic British overdrive is your cup of tea, John Bull's gonna squeeze your lemon so hard it will hurt.

Whether you are looking for Top of the Pops jangle, high-voltage crunch or creamy Woman Tone, John Bull lays the g-spot right at your fingertips.

ToadWorks John Bull is an op-amp based overdrive effect, featuring a unique combination of symetric and asymetric gain circuits. Increasing the Gain control actually changes the character of the overdrive, not just the amount of it. The Mids control spans the decades with one smooth sweep, making John Bull the perfect marriage of versatility and affordability since... well, since the beginning.

The switch turns the effect on and off, the Gain knob controls the amount of overdrive present in the signal, the Mids knob changes the midrange frequency response, the Presence knob controls the amount of presence, and the Level knob controls the overall signal level.

John Bull features a true-bypass circuit, so your bypassed tone stays as clear as an un-mudded lake, as clear as an azure sky in deepest summer - when it comes to tone preservation, you can rely on us! Each pedal is carefully manufactured by hand, using only the finest components.
